Dimension comparison
Overview of the Products
The Greenworks 40V 17" Cordless Lawn Mower and the PowerSmart EasyGlide 21-Inch Gas Lawn Mower are two competitive options for consumers looking to maintain their lawns. The Greenworks mower is priced at $279.99, while the PowerSmart model costs $289.99, making the Greenworks mower about 3.5% cheaper. Both models have unique features tailored to different user preferences, which will be explored in this comparison.
Power Source and Performance
The Greenworks mower operates on a powerful 40V cordless battery system, offering up to 35 minutes of runtime on a single charge. In contrast, the PowerSmart features a reliable 144cc 4-stroke OHV gas engine, designed for high performance and longevity. While the cordless option offers a quieter experience—operating 30% quieter than gas mowers—the gas-powered mower may provide continuous power without the need for battery recharging. This makes the Greenworks ideal for small to medium yards, while the PowerSmart may better suit larger areas or those who prefer not to recharge between uses.
Cutting Capacity and Versatility
The cutting width of the PowerSmart is 21 inches, which is larger than the Greenworks' 17-inch deck. This difference allows the PowerSmart to cover more ground in a single pass, potentially reducing mowing time. Both mowers offer versatile cutting options; the Greenworks has a 2-in-1 system for mulching or bagging, while the PowerSmart provides a 3-in-1 function, allowing mulching, bagging, or side discharge. This added feature from the PowerSmart gives users more flexibility depending on their yard's needs.
Ease of Use
Ease of use is a significant factor for many lawn mower buyers. The Greenworks mower features an instant push-button start and is noted for being lightweight and easy to maneuver, making it user-friendly, especially for those who may struggle with traditional pull-start gas mowers. The PowerSmart includes an easy start system with auto choke and primer, designed for hassle-free operation. However, the added weight of the gas engine might make it slightly more cumbersome compared to the lighter Greenworks model.
Cutting Height Adjustments
Both mowers allow for height adjustments to cater to different grass types and lawn conditions. The Greenworks mower offers six cutting heights, adjustable with a single lever. Similarly, the PowerSmart also features six cutting positions, with dual-lever height adjustment for selecting cuts between 1.5 inches and 3.9 inches. This equivalence offers consumers flexibility in achieving their desired lawn appearance, though the specific height options may slightly differ in practice.
Maintenance Requirements
Maintenance is a crucial consideration when choosing a lawn mower. The Greenworks mower is virtually maintenance-free due to its brushless motor, which eliminates concerns over oil changes or fuel. This not only saves time but also provides a cleaner operation without fumes. In contrast, the PowerSmart gas mower may require regular maintenance typical of gas engines, including oil changes and fuel refills, making it potentially more labor-intensive for the user over time.
Warranty and Reliability
In terms of warranty, the Greenworks mower offers a worry-free three-year warranty on both the tool and battery, highlighting its reliability and the manufacturer's confidence in their product. The PowerSmart mower's warranty details are less specified in the provided data; however, the emphasis on durability with its engineered body structure suggests a focus on longevity. For consumers prioritizing warranty coverage, the Greenworks may present a more appealing option.
Which should you buy?
Deciding between the Greenworks 40V 17" Cordless Lawn Mower and the PowerSmart EasyGlide 21-Inch Gas Lawn Mower largely depends on your specific needs and preferences. If you prioritize ease of use, quiet operation, and lower maintenance, the Greenworks model is a compelling choice at $279.99. However, if you have a larger lawn and prefer the performance consistency of a gas engine, the PowerSmart, priced at $289.99, may be the better fit. Ultimately, each mower has its strengths, catering to different types of users and lawn care requirements.
